Purchased these for my \"She Shed\". These were super ease to install. They snap together. Now I will say I was unable to snap together by hand. In that they can handle upto 55,000 lb, I figured they could withstand me stepping on them. I put down one at a time by lining up the tiles, then stepped on them to lock in place. Worked great and quickly had them installed. My only \"issue\" is I do not see where this brand sells a transition piece for a doorway or a smaller piece for the spacing need to the other wall. The product does state the tiles can be cut to size. I have a few pieces remaining that I will try to cut to fill in the areas that can be seen. So keep this in mind where deciding how many tiles you need to purchase. Also super easy to clean.
